People used to use the dislike counts and compare it with like count to determine if he/she should waste half an hour on this tutorial video. Or if he/she should blindly trust that news clip where the channel have already turned off commenting. This add-on is a very useful tool against YouTube's political decision to protect the face of pro-western news channels on controversial issues.
However, we would be very happy if the add-on gets the free "recommended" badge so non-programmer users can use this great add-on without fear. Thanks to the dev.
